I interviewed in 3 different groups. In each case the interviews were conducted over 1-2 days, consisting of 4-5, hour long, 1:1 interviews. There is much information on the net about Microsoft interview and I'd say the interviews were 'standard' for Microsoft. What surprised me the most about the interviews was the utter lack of professionalism displayed by the first two teams. A couple of examples: - a hiring manager didn't show up for a morning interview and didn't bother to call the coordinator or me - as our rescheduled interview was about to begin, the same manager left me waiting for 15 minutes while he chatted with a team member outside of his office - a second manager left me standing outside of his office for 30 minutes while he loudly chatted on the phone, feet up on his desk, about his weekend. When we started the interview he offered no apology. - about half of the interviewers did not review my resume before we started talking In general, the interviewers were unprepared and unprofessional, even arrogant. I was surprised by the number of sophomoric interview questions and meaningless riddles and almost total lack of interest in exploring my decade+ of highly relevant experience. While I did accept a position in another group, I'd say the overall experience was extremely disappointing and reflects very poorly on Microsoft's culture.
